Per a 2016 Women in the Workplace study by McKinsey & Co. and Sheryl Sandberg’s Leanin.Org (see PDF below), it will be more than a century before there is gender equality in the workplace. The cause, they say, has little to do with women opting out. The latest studies show that attrition is roughly equal between men and women. Instead, women are facing barriers to advancement primarily due to gender bias.
